The archives are named predictably, enabling brute\u2011force enumeration of the ZIP files and the retrieval of personally identifiable information, including financial details. This results in a disclosure of sensitive data, compromising confidentiality.", "risk_and_exploitability": "The CVSS score of 5.3 indicates medium severity. The EPSS score of less than 1\u202f% suggests a low likelihood of exploitation in the wild, and the vulnerability is not listed in CISA\u2019s KEV catalog. Exploitation requires no credentials; an attacker only needs to send HTTP requests to the bulk\u2011download endpoint and systematically try the predictable ZIP names. Successful enumeration would expose a large volume of PII. While the immediate risk to a single site may be modest, the potential for mass data leakage makes this a significant concern for administrators."}}}}, "created": "2026-03-25T11:35:39.180451+00:00", "updated": "2026-03-29T20:28:31.854509+00:00", "vendors": ["peprodev_ultimate_invoice", "peprodev_ultimate_invoice$PRODUCT$peprodev_ultimate_invoice", "wordpress", "wordpress$PRODUCT$wordpress"], "weaknesses": ["CWE-287", "CWE-200"]}
